Why Does a BMW Make a Clicking Sound When Braking?

[IvanAnn]

When a BMW makes an abnormal clicking sound while braking, this is due to the normal activation of the vehicle's ABS system. Additionally, excessive wear on the brake discs and brake pads can also cause noise. Related explanations: 1. Introduction: The actual working process of the ABS in a vehicle is a cycle of locking and releasing—locking and releasing. During driving, the vehicle is always in a state of near-lock rolling. When the brake is applied while driving, the ABS engages, and during its operation, a clicking sound occurs, which is a normal phenomenon. 2. Additional Information: During vehicle use, the brake discs and brake pads continuously wear out. Excessive wear on these components can lead to noise during braking. Both brake discs and brake pads are high-wear items, as they undergo friction with each brake application. If they are not replaced over a long period, the vehicle will naturally produce noise during braking.
